Nacos is hardening the AI registry it just built, and closing the door behind its deprecated APIs.
Nacos has finished turning a microservice registry into a registry for AI agents — MCP, Skill, Prompt and Agent resources all live under one AI Registry — and the 3.2 line is now spending its releases making that surface safe to operate. The newest patch adds server-identity authentication to internal JRaft traffic, puts MCP tool imports from private addresses behind an administrator allowlist, and returns HTTP 410 on deprecated AI APIs by default. The 2.x line runs in parallel as a JDK 8 maintenance branch that receives only backported fixes.
Rivet positions its Actors runtime as the infrastructure layer for enterprise-ready, AI-native application deployment.
Rivet has shipped three substantive capability moves in rapid succession: BYOC (Bring Your Own Cloud, letting enterprises run Rivet's control plane inside their own AWS or GCP VPCs), MCP integration (exposing Rivet Actors as a first-class tool in Claude Code, Cursor, Codex, and Gemini CLI), and Dynamic Apps (a V8-isolate-based runtime for deploying AI-generated applications for end users). Underneath all of this is the Actors model — a durable, stateful compute primitive built on open-source infrastructure. Durable Streams, a zero-disk SQLite storage engine with S3 tiering, and the agentOS execution API round out the technical foundation.

The 2.x line runs in parallel as a JDK 8 maintenance branch that receives only backported fixes.
Two threads are running at once: 3.3.0-BETA is extending the registry to protocol-neutral agent registration and vector-based resource discovery, while 3.2.x closes off the compatibility and security debt that the fast AI-registry build-out accumulated. The breaking notice in 3.2.4 — an irreversible JRaft authentication transition and 410s on legacy endpoints — reads as the project deciding the AI surface is stable enough to stop carrying old shapes. Operator-facing work, not new capability, is where the 3.2 series is heading.
Expect 3.3.0 to go final on the agent-registration and vector-discovery work while 3.2.x keeps shipping security hardening; the temporary nacos.core.api.compatibility.enabled switch is the obvious next thing to be removed.
Rivet has shipped three substantive capability moves in rapid succession: BYOC (Bring Your Own Cloud, letting enterprises run Rivet's control plane inside their own AWS or GCP VPCs), MCP integration (exposing Rivet Actors as a first-class tool in Claude Code, Cursor, Codex, and Gemini CLI), and Dynamic Apps (a V8-isolate-based runtime for deploying AI-generated applications for end users). Underneath all of this is the Actors model — a durable, stateful compute primitive built on open-source infrastructure. Durable Streams, a zero-disk SQLite storage engine with S3 tiering, and the agentOS execution API round out the technical foundation.
Rivet is building toward a single answer to a specific question: where does agent-generated, user-facing software actually run? The BYOC move unlocks regulated industries and large enterprises who can't send data to a SaaS control plane. MCP turns Rivet's Actors into something any AI client can discover and call without bespoke integration. Dynamic Apps makes Rivet the runtime, not just the infrastructure, for user-generated software. The through-line is that Rivet wants every AI agent — whether built by a developer or generated at runtime — to run on the Actors primitive with Rivet managing the lifecycle.
BYOC on AWS/GCP is the foundation; Azure support and SOC 2 certification are the logical next steps to close enterprise deals. Expect MCP to expand to more clients (OpenAI Codex, Copilot, Windsurf) as the MCP ecosystem grows, and Dynamic Apps to get versioning and rollback — the missing piece for user-facing production deployments.
